The Lowdown
Alright folks, Rusty here. Let's be straight with you: this is a tough run for Kennebunk Beach. We’ve got a long stretch of nothing really happening. The first week is a write-off, with poor surf conditions and weak, short-period windswell that won't do a thing for you. Expect a significant gap of quiet, small, and messy water from Sunday, August 23rd, right through the rest of the month. The water temp is sitting about 65°, which is pretty average for this time of year.
There is a glimmer of something different, but you’ve got to be patient. Things start to look a little more interesting heading into the first week of September. On Tuesday the 1st, the morning shows a little life. We’ve got a clean 1.6ft easterly groundswell with a period of 15 seconds, and the wind is a light cross-offshore breeze from the ENE. The energy is moderate (178), and the waves are clean, but it’s still small and only a 'fairly consistent' break. On Wednesday the 2nd, the morning is the real standout. The swell picks up to 2.6ft from the SE, with a period of 12 seconds and a lovely cross-offshore wind from the east. The wave energy is solidly moderate (215), and the conditions are clean. This is probably the best you’ll see in the whole window, but it’s still not a big day.
The long-range part of the forecast has a couple of interesting moments, but they are less certain. The morning of Saturday the 6th of September shows a clean 3ft SSE swell with a 12-second period (energy 363) and a light cross-offshore northerly wind. That’s a decent amount of energy for the sandbar, but the wind is fickle. Then Monday the 7th of September morning is glassy with a 2.6ft ESE swell (energy 126), a total calm morning. It's a promising start to the day, but again, it's a long way out.
Look, overall, this is a quiet period. The best call is the Wednesday morning (September 2nd) at Kennebunk Beach. The swell is biggest of the run, the wind is clean, and the energy is there. It’s not a classic, but it’s the only thing on the menu that looks worth getting wet for. For the rest, keep your board in the car and watch the sky. Don't hold your breath.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
